DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus which forms an image on a sheet surface and automatically glues the image to a printing screen or a back surface where no printing is performed without the need for gluing by hand or the like after printing. Further, the present invention relates to a stacking means for properly stacking the sheets thus glued without being hindered by the adhesive layer.

[0002]

2. Description of the Related Art There are printers of the type in which a double-sided tape is attached to a sheet. For example, as disclosed in WO95 / 13679, there is known an image forming apparatus such as a copying machine which mounts a tape on which an adhesive layer is formed in advance at a position before printing and forms an image on a printing screen of the tape. I have.
Further, an apparatus for feeding and printing a sheet with an overcoated glue has been commercialized.

[0003] Further, as disclosed in Japanese Patent Application Laid-Open No. 1-271367, a booklet is provided in which a specific position on a sheet surface is glued. In addition, in order to prevent the stacking position from being shifted when stacking and storing the sheet on which the adhesive layer is formed and storing the sheet, the adhesive layer is covered with a sheet or the like when the sheets are stacked, and then stacked. Can be

[0004]

However, according to the conventional techniques disclosed in these publications, it is not possible to select a gluing position according to a printing target or a content to be printed. In addition, it is impossible to respond to a demand for controlling the strength of the adhesive force by adjusting the area to which the glue is applied. There is also a demand to make the gluing position and its area variable depending on the direction of the printed characters and the direction in which the sheet is to be attached. Further, even for fixed-size paper, the width and position at which the large and small sheets are glued are different. In a structure in which a sheet whose glue position is set in advance is fed, the position where the adhesive is applied cannot be arbitrarily selected.

[0005] Further, in order to impede the adhesiveness of the portion to which the adhesive is applied and to impair the final stacking alignment, a cover sheet or the like is overlaid on the adhesive layer to make it difficult for the sheets to adhere to each other so that the final stacking is not possible. A device with improved performance has the disadvantage that the cover sheet must be removed at the stage of use after removal.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (General Description of Apparatus)
In one embodiment, as shown in FIGS. 1 and 2A, a gluing unit is provided downstream of the image forming apparatus (printer) and is discharged and loaded. Further, as shown in FIG. 2B, the gluing unit may be located upstream of the print head for printing, or the gluing mechanism may be located at substantially the same position as the print head as shown in FIG.

When the gluing unit 2 is located upstream of the printer 1 as shown in FIG. 2B, printing can be performed when printing is performed while avoiding the position where the adhesive layer is formed. In consideration of this, it is necessary to devise a method in which the adhesiveness does not hinder the movement of the printing head. As one example, FIG.
As shown in (a), a method of forming a coat layer of an overcoat material 131 (sheet, microcapsule 131a, etc.) on the slope 130 with respect to the sheet S, printing, and then removing and stacking the overcoat is conceivable. However, after the adhesive layer 133 itself is sealed in the microcapsule 132 and printed, the microcapsule 1 is pressed by a roller or the like that applies pressure.
A method of taking out the adhesiveness by destroying 32 is also conceivable (FIGS. 20 (b) and 20 (c)).

In the example of FIG. 14, a serial thermal head heats a transfer ribbon and prints by printing.
And a gluing head 120 for gluing are integrally formed. If the printing is performed while avoiding the printing position, the document may enter from the direction of the printing head 120 and print while avoiding the printing position.

As shown in FIG. 20 described above, a form in which the adhesive layer is protected is conceivable, and it is also possible to provide an integrated state while protecting it as in the conventional technique. For example, in the description of FIG. 10 in the description of the embodiment, a protective sheet may be provided instead of the glue sheet 75 for forming the adhesive layer in the loading section. However, as described in the related art, it is desirable that the adhesive layer be exposed and integrated before loading to provide a user with a view to avoid obstacles during use. (Claim 2 and the like) In the following examples, an example in which only the pressure-sensitive adhesive layer is formed after image formation and then integrated is mainly described, but as described above, the present invention is not limited thereto. The present invention includes many forms, with the image forming position and the adhesive layer forming position being in any relationship.

[0014]

Embodiment (Structure of gluing unit) First, the embodiment of FIG. 1 will be described.

The printer 1 is an ink-jet printer, in which a print head is located on the upper surface of a sheet transport and printing is performed on an upper surface of the sheet S. The sheet S printed on the sheet surface by the printer is placed in the sheet feeding port 142.
It is carried in from. The manual feed slot 141 located above the paper feed slot is an inlet for manually feeding the sheet S. A document position sensor 143 is provided in front of the document transport unit.
Paper feed port 142 or manual feed port 141 based on the
The sheet carried in from is transported. The sheet printed by the printer 1 is conveyed by the paper feed roller 144 in the direction of the glue tape head 10 with the print side up via the paper feed port 142.

The gluing unit 2 has a document position sensor 143 for detecting the leading edge of the document, a tape receiving member 13 installed at a position where the document is sandwiched between the glue transfer tape, the glue transfer tape cartridge 46, The glue tape head 10 that can move with the glue transfer tape cartridge 46 mounted thereon, a motor (not shown) for driving the glue tape head 10, a belt (11 in FIG. 3) for transmitting the drive, and the glue tape head 10 This is a gluing unit composed of a supporting shaft (12 in FIG. 3) and a frame 162 for constituting a structural member.

The leading end of the sheet S conveyed into the unit is detected by the document position sensor 143, and the sheet S is conveyed to a position where gluing is to be performed and stopped. A document position sensor 143 is provided in the gluing unit in order to accurately glue the document conveyed into the gluing unit to a predetermined position. The leading edge of the document is detected by the document position sensor 143, and the document is conveyed to the position where the adhesive layer is to be formed and stopped.

The glue tape head 10 is caused to stand by at the side surface position of the document in advance, and the glue start signal causes the glue tape head 10 and the glue transfer tape cartridge 46 to move to a predetermined position corresponding to the document size information.

As described above, even though the sheet S is temporarily stopped, there is sufficient space in the portion of the paper feed port 142 from the printer 1 for the rear end of the sheet to bend while the document is being formed with the adhesive layer. In addition, it is possible to perform the gluing without lowering the productivity of the printer. As a matter of course, in order to increase the productivity, the tape head 10 may be made to stand by at the mounting start position in advance while the document is being transported.

FIG. 5 shows the internal structure of the glue transfer tape cartridge 46. The glue transfer tape 45 and the glue transfer tape 4
A rotating shaft 34 for holding and winding 5 and a glue transfer tape 45
And a cover 46a for incorporating the rotary shaft 34 therein. FIG. 3B shows the structure of the paste transfer tape 45. The base material 43 on which the glue is placed and the base glue 40 attached to the base material 43 side
And a sheet glue 41 attached to the base glue 40.
As a result, the sheet glue 41 is stuck to the document surface, so that the adhesive strength is strong, and the base glue 40 can select a glue material whose adhesive strength is changed according to the application. For example, when using glue that can be pasted and peeled off, an adhesive material having low adhesive strength is selected.

A glue transfer tape cartridge 46 is mounted on the glue tape head 10, and a glue transfer tape 45 having an adhesive layer previously formed on a base material is wound inside. (Transfer Tape Roll 33) The adhesive layer of the paste transfer tape 45 has perforations 42 at a predetermined pitch, and the formation of the adhesive layer can be appropriately stopped and started without using a cutter or the like. .

In FIG. 3, since the glue tape head 10 forms the adhesive layer in a direction perpendicular to the transport direction, the transport of the sheet S is stopped while the adhesive layer of the line is being formed (arrow A2). (Arrow A1).

Further, even if the perforated structure shown in FIG. 5B is not used, the structure of the adhesive layer is made into fibers so that it can be easily cut in the longitudinal direction. Only can be formed. By starting formation a plurality of times from the predetermined position of the head position in the sheet conveyance direction, it is possible to form the adhesive layer in an arbitrary area on an arbitrary position on the sheet surface.

At the same time that the tape head 10 starts operating along the head shaft 12 by the belt for transmitting the drive, the glue tape roller 35 shown in FIG. 5 moves to the original side, and the glue transfer tape 45 and the tape receiving member 13 The sheet S is interposed therebetween. Tape glue tape head 10
Is driven in engagement with the tooth surfaces 11a and 11b of the belt so as to travel in a direction opposite to the moving direction (arrow 2), and is wound around the rotating shaft 34, and the glue is transferred to the document.

In the above example, the glue tape head 1
0 is accessed and attached from the lower side of the document (the side opposite to the printing side), but can also be accessed from the upper side as shown in FIG. In this case, with respect to the stacking and storage utilizing the adhesiveness described later, the transport member 26 having the transport adhesive portion 20a above is transported by the arm 27 along the transport shaft 23 by the belt 24 driven by the motor 25.
The solenoid 22 and the link 21 are connected to the sheet S by the transport bonding unit 2.
0a is moved up and down.

Even when there is a printing surface on the upper surface, it is necessary for applications such as displaying the printing surface on a transparent display such as a window glass.

The formation of the adhesive layer is not limited to the glue tape, but may be a coating method (FIGS. 11 and 13) or a spraying method (FIG. 12). The method of FIG. 11, FIG.
Although the method 3 has a fixed width, the area can be formed without stopping the conveyance of the original, and the two are only different in width.

In FIG. 11, the guide plate 80 and the glue tank 81 for preventing the skew of the transport are synchronized to control the gluing position. In both cases, the bleeding portion 81a for gluing is configured to be rotatable upward and downward, and as shown in FIG.
By switching, the surface on which the adhesive layer is formed can be switched.

(Structure of Stacking Means) An example in which the sheet on which the adhesive layer is formed can be stacked and accommodated by a protective sheet or the like without excluding the influence of the adhesive layer will be described below. FIG. 2 (a),
The loading means 3 in FIG. 2B is the loading means 3 in FIG.

The glued sheet S is conveyed into the stacking means 3 and is conveyed to a deflecting roller 149 which conveys the sheet in a conveyed direction while deflecting it in an arc shape through a conveying path 146. A spur roller 147 is provided on the gluing surface side (lower surface) of the transport path 146 to prevent glue from adhering and causing transport failure. The spur roller 147 has a plate-like disk shape that is sufficiently thin with respect to its diameter, and has a saw-shaped tooth on its circumference. Although the teeth are formed in order to reduce the adhesion area to the document surface, this is not limited to a disk shape having saw-shaped teeth. For example, a shape in which a needle stands on a cylindrical surface is also conceivable.

A positioning sensor 153 is provided in front of the deflecting roller bonding portion 149a of the deflecting roller 149 so that the position where the sheet S is attached can be positioned at the deflecting roller bonding portion 149a. The motor 7 is a stepping motor. The original position sensor (60) detects the leading edge of the original (FIG. 8A), and after a predetermined number of steps of conveyance, the deflecting roller 149 rotates in the conveyance direction together with the conveyance of the sheet S. The process starts (FIGS. 8B and 8C).

A plurality of deflecting roller bonding portions 149a are arranged at appropriate intervals in a direction perpendicular to the width of the sheet S in the conveying direction, and the shape of each deflecting roller 149 bonding portion is limited to a portion where the sheet S is glued. Are present in a fan shape on the circumference of the deflecting roller bonding portion 149a so as to be in contact with. The fan-shaped arc is the bonding portion and the other is the non-bonding portion. However, even a member having a circular cross section can be realized by controlling the bonding property by selecting the material of the bonding portion and the non-bonding portion.

Referring to FIG. 6, a plurality of spur rollers 51 exist between the deflecting roller bonding portions 149a arranged at a certain interval so as to be driven by the sheet discharging roller 50. The peeling bar 57 is provided with a deflecting roller 149.
Is provided below the deflecting roller 149 at such a position as to sandwich it.

The paper discharging roller 50 includes a foaming roller 50a made of a stretchable elastic material and a foaming roller 50a.
A rubber roller 50b having a moderately high hardness with respect to a is formed, and the foaming roller 50a is positioned so as to abut the deflecting roller bonding portion 149a and the rubber roller 50b abuts the spur roller 51.

The front end of the pasted document is sandwiched between the foaming roller 50a and the deflecting roller bonding portion 149a, and is securely attached to the deflecting roller bonding portion 149a.

The circumferential locus of the discharge roller 50 and the circumferential locus of the deflecting roller bonding portion 149a intersect each other on the center line of both by an arrow I (fitted by projection in the direction of the rotation axis) (FIG. 7).
(A)). Further, the foaming roller 50a of the sheet discharging roller 50
Is softer than the material of the deflection roller bonding portion 149a. Therefore, when they cross each other, the foamable rollers 50a
Are deformed along the circumference of the deflecting roller bonding portion 149a (FIGS. 7B and 8B). An elastic pressure is generated between the two contact surfaces. The glued portion of the sheet S sandwiched between both
With the pressure generated by the above-mentioned intersection, the adhesive is securely bonded to the deflection roller bonding portion.

For bonding, the leading end of the document is attached to the deflection roller bonding portion 149.
a, and the sheet S downstream therefrom is conveyed by the rubber roller 50b and the spur roller 51 so as not to contact the side surface of the deflecting roller 149 (FIGS. 8D to 9A). For example, the original is sent out by the rubber roller 50b and the spur roller 51 at a speed higher than the peripheral speed of the front end of the bonded sheet S.

The leading end S1 of the sheet S adhered to the deflecting roller bonding portion 149a is guided downward in the roller rotation direction. (FIGS. 8C to 8D) At the same time when the leading end S1 of the sheet S reaches the rising surface 61a of the stacking portion 61 (FIG.
(D) to FIG. 9 (a)) The peeling pawl 57 rotates in a direction to press the sheet S against the stacking portion 61, and presses the sheet S (FIG. 9 (b)). Since the leading end S1 of the sheet S is fixed, when the deflecting roller further promotes the conveyance, the sheet S after the bonding portion is discharged while changing its upper surface and lower surface in the direction of the paper discharge tray 62 (FIG. 9 ( c)). The interchange of the upper surface and the lower surface in this way also serves as a so-called inversion mechanism.

When the discharge is completed, the peeling stick 57 returns to the standby state diagram (FIG. 8A). When the trailing edge of the sheet S passes through the discharge roller 50 in a state where the leading end of the sheet S is pressed by the peeling clasp 57, the sheet S falls on the discharge tray 62 with the stiffness of the sheet S, and the printing surface is lowered. It is loaded with the gluing surface up. (FIG. 9C) When the discharge is completed, the peeling pawl 57 waits for the next sheet S at the original position.

The loading section 61 is operated in the same manner for the second and subsequent pages.
And loaded at any time with the tips aligned.
(FIG. 9 (d)) Since the sheet S sent from the printer is printed on the upper surface, if the sheets are stacked as they are, the order of the pages is reversed.

(Example in which gluing and stacking functions are integrated) Next, an embodiment in which formation of an adhesive layer and stacking of sheets are performed simultaneously will be described with reference to FIG. In this embodiment, the formation of the adhesive layer and the stacking of the sheet S on which the adhesive layer is formed are performed at the same time, so that a more compact glue stacking is performed.

A glue roll 73 on which the glue tape is wound, a glue tape 75, a take-up roller 74 for winding the glue tape, a deflecting roller 70 for deflecting, and a pressing roller 72 for pressing the glue tape against the document. It is composed of

As shown in FIG. 10A, when the sheet S is conveyed to the lower portion of the discharge roller in the face-up direction, the sheet is wound between the deflecting roller 70 and the discharge roller 76 in the cartridge 71. 75 and starts rotating together with the pressing roller 72. At this time, pressure is applied between the discharge roller 76 and the deflecting roller 70, so that the tip of the deflecting roller 70 adheres to the adhesive layer formed on the document,
The document is deflected and conveyed to the lower part while being wound up by the deflecting roller 70. (FIG. 10 (b)) When the deflecting roller 70 is disengaged from the paper discharge roller 76 and the pressure roller 72 falls on the lower part of the paper discharge roller 76, the pressure roller 72 stops at that position and is placed on the back surface in the downstream direction of the document. The original is transported together with the paper discharge roller 76 so as to transfer the original. (FIG. 10 (c)) When the leading edge of the document is conveyed to the rear end (FIG. 10 (d)), the deflecting roller 70 is stopped, and the document is further conveyed by the discharge roller 76 and the pressing roller 72, and the document is conveyed. It stops when all the gluing is completed. (FIG. 10E) When the original is conveyed to the vicinity of the rear end of the sheet S, the gluing is completed, and the pressing roller 72
Rotate as shown by the dotted line in FIG. Thereafter, the deflecting roller 70 waits for the next sheet S at the specified position together with the pressing roller 72. (FIG. 10 (g)) In the above description, an example has been shown in which the glued sheet S is bonded and transported, and the transport direction is deflected for final placement. However, the deflection is not necessarily required. Whether or not to deflect is determined by whether or not the upper surface of the stack at the time of loading is the same as the upper surface at the time of transport. As shown in FIG. 4, parallel transport may be used.

In particular, when the printing technique uses ink that is not quick-drying, the ink may contaminate the transport path and affect the subsequent image quality. At this time, the printed surface is dried from above by holding it on the upper side until it is loaded.

On the other hand, in thermal transfer printing of a thermal head or the like, since there is no such concern, printing may be performed on a lower surface. When printing is performed on the lower surface, the pages are not disturbed when the sheets are stacked in the transport state, and are used particularly in applications such as facsimile and OCR.

In this case, since the back side of the print is located above the original transport, there is also a use for forming an adhesive layer on the upper side. The embodiment of FIG. 4 can be used in such a case, and performs adhesive transfer like suction transfer of a silicon wafer.

(Modification of Gluing Portion) As shown in FIGS. 11 to 14, it is possible to carry out gluing other than tape-shaped gluing, and the following example will be described.

FIG. 11 shows an example in which a head that contacts the sheet S and applies glue is used, as in FIGS. Glue tank 81 filled with liquid glue
Is fixed to the tank shaft 83, and changes its direction freely according to the rotation of the tank shaft 83. Therefore, when the sheet S is conveyed straight, as in the path P1 in FIG. 11B, the glue tank 81 is positioned above, and the bleeding portion 81a comes into contact with the lower surface of the sheet S to glue. Is performed. Further, the flapper 82 is switched in the direction of bending downward like the path P2, and the glue tank 81 can change the direction downward so that the seepage portion 81a abuts on the upper surface of the sheet S to perform gluing.

Further, the glue tank 81 may be formed as a pair in the width direction of the sheet S as shown in the figure, and may be one or three or more. The glue tank 81 is configured in conjunction with the guide plate 80 that regulates the width direction of the sheet S, and can be glued at a position corresponding to the sheet width.

Next, referring to the example of FIG. 12, a spray tank 90 containing exchangeable compressed gas is provided.
The spray port 90a is attached to a flow control valve 91 provided with a spray nozzle. The spray tank 90 is fixed by the clip 92a attached to the frame 92. The frame 92 is movable in the direction of the frame shaft 94 in cooperation with the frame shaft 94 and the belt 95.

The spray paste sprayed from the flow control valve 91 passes through an area control throttle 93 and is applied to the sheet S.

The example of FIG. 13 is basically similar to the example of FIG. 11, but is an example of a head that enables longitudinal attachment in the sheet width direction. A paste space 109 is provided inside the paste case 101, and a balloon 110 which expands by gas pressure is incorporated therein. This generated pressure presses the valve element 104, but when the motor M rotates the shaft to bring the head 100a into contact with the seat, the valve element 104 is pushed down against the spring 102 to exude the paste.

FIG. 14 is a little earlier, in which a transfer type print head 126 and a press-adhesive type glue head 120 are formed on the same frame 121. The gluing head 120 includes a solenoid 122, a cam 123, a spring 12
It is moved up and down in cooperation with 4.

(Explanation of the control unit) As described above, in each sequence such as the mounting of the sheets on the sheet and the placement of the mounted sheets on the tray, the sensors installed at the respective main points are used. The actuator such as a motor is controlled on the basis of the above signal. Control means is used for this control.

FIG. 15 shows a general control block diagram, and the present invention is not limited to this. The gist of the present invention is only required to be a configuration that enables optimal bonding, and does not depend on an image forming apparatus such as a printer.
Further, the control has been described with reference to FIGS. 16 to 19, but this is merely an example of how to move, and does not restrict the idea presented by the inventor. For example, there is no necessity for a gate array to perform sequence control, and neither computer control nor semi-manual operation with a panel intervenes to restrict the idea.
